UD police will conduct one demonstration at 8:30 a.m. Thursday in the UD Arena parking lot and at 3 p.m. at the same location, according to the campus alert called Flyer Aware.

The university is preparing for the NCAA First Four games at UD Arena and St. Patrick’s Day, which is Sunday.

St. Patrick’s Day celebrations at UD have sometimes led to large crowds. The Flyer Aware alert did not indicate whether UD police would ue the LRAD on the holiday.

Last year, students on Lowes Street reportedly threw objects at police and shot fireworks into crowds of people on the March 17 holiday. By 6:30 p.m. last year, officers arrived in riot gear and ordered parties indoors, though many at first ignored those commands.
